Nmr-based chromatography readouts: indispensable tools to “translate” analytical features into molecular structures

HIGHLIGHTS

SUMMARY

    The interpretation of MS signals, e_g, the correlation with the structural features of the investigated molecules or the derivation of a molecular formula, strongly depends on the instrumental design of the mass spectrometer used. In the case of linearly organized bio-macromolecules with a limited number of building blocks (e_g, peptides, proteins, and DNA/RNA oligomers), it is possible to analyze the fragmentation of the molecules in the mass spectrometer in such a way that the sequential arrangement of the building block elements can be deduced. If 13 C-NMR spectroscopy is utilized, e_g . . .
